The study was conducted to determine the soil fertility status of Karchhana Block in Prayagraj District (U.P.). The current study, "Soil fertility mapping of Karchhana block, Prayagraj," was conducted in 2022-2023 and involved the collection of twenty-seven soil samples from the nine designated locations from various places covering the whole block and sample points were tagged through Map-INR software. The laboratory tests for analysis of soil properties were carried out at the CSSRI, Karnal and at the department of soil science at the Naini Agricultural Institute. The results of primary and secondary nutrients in the soil samples were then mapped using Arc-GIS software (10.4.1) by assigning three fertility classes, low, medium, and high combined with GPS co-ordinates and the rest area was interpolated by Arc-GIS. The soil fertility maps clearly revealed that the study area is moderate in fertility status with medium ranges of macronutrients in the sample. The observed area was sufficient in N, P, OC, Mn, and Mg but low in S. Through maps, the farmer and agriculture professionals can take advantage of the technology for the betterment of the sector and the nutrient status of a broad area can be known digitally. This idea was undertaken from the recent projects of NBSSLUP.
